Geissele SSA-E Super Semi-Automatic Enhanced AR-15 Trigger

The great thing about an AR-15 is how modular the components are. I recently upgraded my 6.8 SPC II from the stock Rock River Arms National Match trigger to the Geissele Super Semi-Automatic Enhanced trigger. Bill Geissele was kind enough to send me his SSA-E trigger for evaluation (along with a cool Geissele Automatics t-shirt).

Geissele Automatics has a wide variety of triggers to choose from. My goals in selecting a trigger were primarily to improve long range accuracy while hunting and precision shooting when testing optics for TGR. Running 3 Gun matches was secondary. I love a crisp, clean break but there is a point when trigger pull/break can be too light in hunting conditions. The Geissele SSA-E seemed to be the perfect choice for both hunting and competition.

Installation was a snap following the included instruction sheet. Basically a drop-in job. I lubricated the trigger and ran through a dozen or so dry-fires. The Super Semi-Automatic Enhanced is a two-stage trigger. According to Geissele, the first stage is 2.3 lbs with the second stage 1.2 lbs for a total trigger pull weight of 3.5 lbs. My RCBS trigger pull scale indicates an even lighter pull weight – first stage of 1.75 lbs, second stage breaks at 2.5 lbs. I’ll trust that Geissele has a more accurate scale than my spring-loaded job but nevertheless it is a wonderful trigger. The first stage provides a level of control and safety. The second stage is “candy-cane” crisp for precision shooting.

Of course, you can also slap through the Geissele SSA-E on close-in rapid-fire targets.

The trigger performed flawlessly at the range. I moved back and forth between precision target shooting and banging steel and was very impressed with how well the Geissele Automatics SSA-E performed. It was a pleasure to shoot in either mode. Anyone looking to upgrade their AR-15 would be wise to invest in a Geissele Automatics trigger.

The full-power hammer spring allows for ignition of even the hardest primers, such as those used in Russian surplus 5.45x39mm. I’ve used a Geissele SSA-E in my 5.45 AR-15 for years. After about 8,000 rounds, the hammer spring needs to be replaced, but once that’s done, the thing continues to run like a champ. I recently upgraded to the flat bow model, the SD-E.
It’s heavenly.
